COIYIBINATION ROASTEB, AND MIXER.

Application filed August 6, 1928'. Serial No. 127,523.

Mv invention relates to a new and useful improvement in a combination roaster and miner adapted particularly for roasting peanuts. The invention has for its object the pro vision of a combination roaster of this kind provided with a hopper from which the pea nuts may be dispensed when sold, the hopper being heated by the same medium used for heating the oven or container in which the peanuts are positioned until the roasting process. I

Another object of the invention is the pro vision of a roaster of this class having a roasting oven or container provided with a mixer for reagitating the peanuts during the roasting process.

Another object of the invention is the provision of a roaster of this class which will be simple in structure. economical ot manufacture and highly efiicient in use.

Another object of the invention is the provision of a roaster of this class which will be so constructed as to require the minimum amount of heat in the roasting operation and tompact so as to occupy the minimum amount of space.

Other objects will appear hereinafter.

The invention consists in the combination and arrangement of parts hereinafter described and claimed.

The invention will be best understood by a. reference to the accompanying drawings which form a part ot'this specification and in which.

I Fig. 1 is a invention.

Fig. 2 a sectional view taken on substantially line oi Fig. 1.

Fig. 3 is a sectional view with parts broken awav taken on substantially line S of Fig. 2.

Fig. it is a sectional view taken on substantially line 4-s1 of Fig. 1.

Fig. 5 is a fragmentary sectional view taken on substantiall line of Fig. 2.

As shown in the drawings there is provided a tripod 9 projecting upwardly from which is a supporting stem 10 provided with a yoke. the legs 11 and 12 01 which are secured to the base of a housing 14-. Positioned ithin the housing 1% an oven or roasting container 15 having in its upper wall loan opening 17. Projeci'ng upwardly around theopening 17 a flange 18 which engages the top wall 19 of the casing, which side clcwational view of the,

thus provided is packed with asbestos is also provided with an opening 20 in registration with the opening 17 A removable cover 21 provided with a handle 22 is used as a closure for the opening 20. Formed in the base 23 of the oven is an opening 2 1 for which there is provided a closure 25 swingably mounted and operable by the hand wheel 26 which is mount ed on the shaft 27, so that the closure 25 may be opened at will. Projecting upwardly from the base 13 are side walls or flanges 28 which serve a chute for conducting material from the oven through the opening 2% and through the opening 29 formed in the base to a hopper 30 which is mounted on the base. This hopper having a forwardly inclined bottom wall portion 31 terminating in a neck 32 which is open at the top and provided with a closure 33, the front wall of this hopper being preferably formed of transparent material. The wall 35 ot' the oven is provided with an extended I portion 36 having the angularly turned portion 37. .As clearly appears from Figs. 2, 3 and 5 the oven 15 is spaced from the casing 14 and the space 38 or other material nonconducting as to heat: Formed on thc'bottom wall of the oven are a plurality of sleeves or tubular supports 39 in which may be positioned a heating elen'ient 410 suitably connected by means of the wire 41 to a source of electrical energy.

Projecting into the oven 15 is a shaft 42. Positioned in the oven is an agitator or mixer comprising a bar 33 having a boss 14: pro jecting downwardly from its underaurtace. the shaft 41-2 engaging in a bore formed in said boss and secured therein by means of the set screw 15 so that a rotation 01 the shaft 4-2 will etlcct a rotation in the oven 15 ot the bar 413. This bar 13 has a downwardly extending portion 46 which at its end is provided with the angularly turned portion 4-7. Projecting, downwardly from the opposite end Off the bar 413 is a leg 48 which is connected to a horizontally extending plate or bar 19 positioned in close proximity to the bottom of the oven 15. The portions 47 and 49 serve as agitators as ,do likewise the downwardly projecting portions 1-6 and 48 so that when the shaft 42 is rotated the peanuts or other articles placed in the oven 15 will be constantly agitated so as to prevent burning etc. Fixedly mounted on the shatt 42 exteriorly of the housing 14 is a gear 16 which meshes with a pinion 47' fixedly mounted upon a shaft 48 which is journalled in an upwardly projecting guide sleeve 49 extending from the top 50 of a housin Fixedly mounted upon the shaft &8 is a worm wheel 51 meshing with a worm 52 which is fixedly mounted upon the shaft 53 of the electric motor 54.

In use the cover 21 may be removed and the peanuts or other articles to be roasted deposited in the oven 15 and the heating elements 40 energized to heat the oven. The motor 54 may then be set into operation so as to rotate the agitating member in the oven 15 to keep the peanuts or other articles stirred so as to prevent burning etc. \Vhen the roasting process is finished the contents may be deposited through the opening 24. into the hopper 30, from which they may be removed as desired by removing the cover 33.

It is thus seen that the structure is one which affords a device for roasting peanuts and also provides a dispensing hopper from which the peanuts may be sold. The heating elements 40 will serve to retain the peanuts in the hopper warm so that they are always retained hot, the advantage of which is obvious.

The structure of the device is believed to be quite simple and one which, while serving the double purposes mentioned, is compact so as-to occupy but little space.

While I have illustrated and described the preferred form of my invention, I do not wish to limit myself to the precise form of structure shown, but desire to avail myself of such variations and modifications come within the scope of the appended claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
